i Application filed January 16, 19218. Serial No. 247,184.

My invention relates to heating and ventilating, and more particularlyto a humidor .or` water reservoir to be suspended behind a l steam orhot water radiator for lmoistening v 5 the warm air.

It is more or less common practice to support a water reservoir orhumidifier behind a radiator in the narrow space between the radiatorandthe wall of the room and at a l level a considerable distance belowthe top of the radiator.v This makes the Vreservoir quite inconvenientto refilly and hence such reservoir or. humidifier becomes quite hotthrough contact with the radiator and it canlV not be readily removedfor replenishing the water sup ly. The present invention affords afilling tube telescopically mounted in the reservoir or humidifier,which may be withdrawn therefrom to sufiicientextent to project abovethe top ofthe radiator and which will serve to direct the water vsupplyinto the reservoir. Stop means isprovided for limiting the sliding ortelescopic movementV ofv the filling tube. When not in use such fillingtube is depressed within the i reservoir. 1

The object of the invention is to simplify the means and inode offilling humidifiers or water reservoirs suspended upon radiar torswithout the necesslty of removing the reservoir and to provide atelescopic filling tube thereforybyfwhich the reservoir may befilledwithout spilling.

A further object of the invention is to.

provide improved means forconnecting the lling tube `with the reservoirand vfor mounting and sliding such tube therein.` c

With the above primary and other incidental objects inview as will morefully appear in the specification, the invention consists of thefeatures of constructiointhe parts and combination thereof7 and the modeof operation, or their equivalents as herein'- after described and setforth in the claims. Inthe accompanying drawings wherein is shown thepreferred,`but obviously not necessarily the only form of embodiment ofthe invention7 Fig. l is aperspective view of a radiator to which awater reservoir or humidifier as herein described has been vapplied.Fig. 2 is a perspective view of the reservoir or humidifier removedfromr the radiator. Fig. 3 is a detail sectional view illustrating themounting of the tube and its range of adjustment.

Like parts are indicated by similarr characters of` referencethroughout-the severall j 2. This humidifiercomprises a tank of rathernarrow but deep proportions, one wall of which. is langularly corrugatedforming a series of spaced bays to project intermediate succeedingradiator sections inv order thatv the reservoir'may approximatelyconform to the radiator l, presenting a yheating surface of increasedarea invclose relation thereto. The reservoir or vhumidifier` is`suspended from the top of lthe lradiator yby hook arms 3. These arms?)are attache/dto the rescrvoir 2 and engagedl withvr the radiatorstructure to support the reservoir or humidifier in a suspended positionwell below the topl of the radiator.` Inasmuch as the radiator is lordinarily set, in close relation with theside wall of the rooni, thehumidifier or reservoir 2 hangs in ,a rather narrowuspace in which itVis not eas'ilyaccessiblefor replenishing Vof the water supply.y Becausethe humidifier or reservoiris ordinarily heated to a highdegree due toits close association with the radiator l it cannot be safely removedfrom such position `without vdanger of buri'iing the fingers.. of theyoperator.. Such humidifier reservoir per Vse forms no part of thepresent invention which pertains primarily to means for conveniently andsafely replenishing the water supply of the reservoir. j

To facilitate thed filling of the reservoir or Y'humidifier 2 andavoidfthe danger ofspill- Y ing the water or burning theffingersoflthegoperator, there is provided a filling. tube x4 of substantiallytriangularV contour conforming to one of the angular corrugat-ions ofthe .reservoir or tank 27 within which it is lon gitudinally slidable.This filling tube is normally positioned within the reservoirorhumidifier'2 with its lower end resting upon the-bottom of the reservoirand its top eX- tending substantially level with the top' thereof. Theupper end of the tube 4 is provided kwith a bail 5 which may be engagedby a hook or other' device for lifting the tube 4. The tube 4 iswithdrawn from the reservoir when itl is desired to replenish the watersupply. Whenso extended the upper end of the tube will projectsubstantially `level with, or preferably slightly abovovthe v I level ofthetop of the `radiator l. In this position, water can be easily andaccurately poured into the top ofthe filling tube by which it isconducted into the reservoir 2 Without danger of spilling. Thereciprocatory filling tube l is provided with a stop shoulder 6 adjacentto its lower end-Which engages With an inturned margin or flange 7 atthe top of the angular corrugation Within which the filling tubeperforms its telescopic 1novement. Such engagement ot the stop shoulder6 with the inturned flange 7 f limits the Withdrawal of the tube andinsures ample overlapping engagement "when the tube is extended toprevent spilling the Water over the side of the reservoir.

From the above description it will be apparentthat there thus provided aconstruction of the character described, possessing the particularfeatures of advantage before enumeratedk as desirable, but whichobviously is susceptible of modification in its form, proportions, andarrangement of parts, Without de arting from the principle involved orsacrificing any of its advantages.

While in order to comply Wit-h the statute the invention is described inlanguage more or less specific as to structuralfeatures it is to beunderstood that `the invention is not c limited to the specific detailsshown, but that the means and construction herein disclosed comprise thepreferred form of several modes of putting the invention `into effect,and the invention is therefore claimed in any of its forms ormodifications Within the legitima-te and valid scope of the appendedclaims.

Having thus described my invention, 'I claim:

l. The combination with a reservoir7 one side of which is singularlycorrugated to approximately conform to the side of a steam or hot Waterradiator and having an open top7 of a t'iangulalr filling tube slidinglyengaged in one of theangular corrugations, a stop on said tube', andan'inturned flange upon the engaged corrugations of theV reservoirlimiting the vWithdrawal of the tube 'therefrom7 a bail connected withthe top of saidtube to facilitateits n'fitlidrawal from the reservoir,said tube being open at its op-V proximately tothe t-op of the reservoirwhen extended through which Water may be conveniently introduced intosaid radiator, said tube having sliding Venga-genuini with the sidewallofthe reservoir and being retractable Withinthe reservoir When not inuse.

3. Thevcoinbination with a .reservoir for mounting upon the side of asteam'or hot Water radiator having a vertical guide recess Aformed in a.lateral Wall thereof of an extensible and contract-able filling'tube forsaid reservoir slidingly engaged Within the vertical guide recess,Which, when extended reaches approximately tothe 'top of the radiatorand when retracted is substantially concealed AWithin the reservoir.

Ll. The combination With a reservoir and suspension members thereforfoi."siipporting the reservoir in' depen-dent position from the top of asteam or hotl water 4radiator of a filling tube for the reservoir thelength of Whichis approximately equal to that of thereservoir'suspension members, theuvall of the reservoir being formedinte van outwardly projecting bay, saidtube being slidvinglyengagedwvithin said outwardly projecting bay of the reservoir forlongitudinal movement in ya vertical direction relative thereto by whichthe upper end of the tube is projected into proximity to the top of the1 radiator for convenience in filling the re."- ei'voir through saidtube.` Y

In testimony whereof, I have 'hereunto set my hand thisf28th day ofDecember A. l). 1927. i Y' .i
